Commercial Shingle Roofing in San Antonio, TX

Plenty of people assume every business roof is flat. Drive down Broadway or McCullough and you'll see otherwise. Law firms, dentists and insurance agents work out of old houses with pitched roofs, and a lot of churches and clubhouses are covered in the same architectural shingles you'd find on a home. That's commercial shingle roofing, the steep-slope half of our commercial roofing work. The shingles are familiar. The job isn't. There are more squares, more people walking in and out under the crew, and an owner or a board who needs a written scope before anybody climbs a ladder. Somebody has to plan the work around open hours, and the crew has to be big enough to finish instead of dragging on for two weeks. Here's who calls us most:

• Professional offices in converted homes along Broadway, McCullough and the side streets around Alamo Heights.
• Churches, fellowship halls and parish offices, a lot of them with tall, steep naves.
• HOA clubhouses, pool houses, rec centers.
• Daycares, small clinics and vet offices sitting on a residential frame.
• Strip centers from the 1970s and 1980s with a shingle mansard wrapped around a flat roof.

Watch out for that last one. Customers see the mansard, but the flat roof hiding behind it is what handles the rain. We get up on both. If the low-slope part needs attention, it goes on the same estimate under our flat roofing scope.

Same shingles. Different job, mostly because of how big the roof is and who's inside.

Size and pitch. A church roof might be three or four times the squares of an average house, at a pitch nobody can walk on. So we bring roof jacks, toe boards, harnesses and extra people, and the estimate spells out what that staging costs.

People underneath. You can send a homeowner to the movies for the day. You can't do that with a room full of toddlers. The dumpster and the shingle drop go away from the doors, customers keep a clear path in, and someone runs a magnet over the lot every evening to pick up nails.

Ventilation. A big open attic over an office or a hall turns into an oven in a South Texas July. We look at intake and exhaust every time. Stale, hot air cuts years off the shingles and pushes the electric bill up.

The joint between systems. If you asked us where commercial roofs leak most, we'd point at the seam where a shingle slope runs down into a low-slope section. We tie the shingles into the membrane (on newer buildings it's often TPO) and flash that transition as a single detail.

Should you pay more for impact-rated shingles? On most commercial roofs in Bexar County, we think so. Hail hits this county a lot, and a big roof turns into a big claim. And a replacement costs more than what's on the invoice once tenants, members or patients spend days working around a crew. Owens Corning and GAF both sell impact-rated lines that go on just like their standard architectural shingles. According to the Texas Department of Insurance, some insurers discount premiums for impact-resistant roofing. Get the actual number from your agent before deciding. On a commercial policy, that discount can cover a good chunk of the price difference over the roof's life.

1. Free estimate. We measure, check the decking from the attic side when we can get in, and write down every vent, skylight and wall joint.
2. Written scope. Shingle line, underlayment, decking allowance, ventilation and flashing, laid out so an owner or a board can sign off.
3. Schedule. We settle on work hours and staging spots, plus any days the building needs quiet.
4. Tear-off and install. We only strip what we can dry in before dark, swap any soft decking, then install the Owens Corning or GAF system.
5. Walk-through. Flashing gets a last look, gutters get cleaned out, and we walk the finished roof with you.

When hail is the reason for the job, the claim runs at the same time. We keep both on one calendar so the crew doesn't tear anything off before the carrier sees it. On a commercial roof that's a real concern, since an adjuster may want to walk a huge field and look at the gutters, the vents and the mansard too. We bring 30+ years of insurance claim experience, and the six steps are on our insurance claims page. Got one leak, or a few blown-off shingles? Commercial roof repair will cost you less. We'd much rather fix a valley than sell a roof you don't need.
